Errors
R0087: "Failed to log in. Could not authenticate. There was a network issue."
R0088: "Failed to log in. Could not log in. Unable to establish a secure connection."
R0090: "Failed to authenticate. Could not authenticate. There was a network issue."

Description
- Error when logging in PIX4Dfields.
- Error when starting a trial period.
- Error when trying to download satellite images.
Cause
There is a proxy/antivirus/firewall on the PC that does not allow the application to validate the HTTPS certificate chain. As a result, communication with the PIX4D server is impossible.
Solution
To solve the problem, the user (or system admin) needs to add an exception to the proxy/antivirus/firewall for one of the following options:
- PIX4Dfields (Windows or macOS)
- Domains:
- Must be reachable without HTTPS inspection (no TLS interception / certificate substitution):
- *.pix4d.com
- *.*.pix4d.com
- *.*.*.pix4d.com
- services.sentinel-hub.com
- Must simply be reachable over HTTPS :
- field-reports.jkvc.de
- *.deere.com
- *.johndeere.com
- s3-accelerate.amazonaws.com
- *.amazonaws.com
- *.*.amazonaws.com
- *.*.*.amazonaws.com
- Must be reachable without HTTPS inspection (no TLS interception / certificate substitution):
Information: The exception should be either for all ports OR port 443 (HTTPS).
